Augment Code is positioned for large codebases: index and understand the repository first, then let the agent find related code, explain module relationships and propose cross-file changes, through both IDE and command line. It targets multi-person engineering environments and cares about retrieval quality and team conventions. Such tools differ most on very large repos, so test with the old problem you struggle to trace; route changes through normal review.
What it does
- Repo indexing with answers across module calls
- Agent edits producing changes in several places
- Both IDE and command-line entry points
- Team-oriented, with shared conventions and context
- Changes shown as diffs for piece-by-piece review
Who it is for
- Large monorepos where one feature touches a dozen files
- Cross-team API changes that need all callers found
- Newcomers building an overall picture of a large project
- Combining retrieval and editing in one tool
How to get started
- Ask without editing first, testing retrieval on real old problems
- Then make a small cross-file change and compare each diff
- Fix team review rules before widening use
